If the weather is good and the usage is low, the problem might come from the solar panel, in that case, refer to the section below
for further information on how to solve the problem.
9.4. Solar panel level always low
If the solar panel indicator is low (below 40%) even when there is a lot of sun shining on the solar panels or if the battery never
reaches a high level of charge, there might be an issue with the solar panel positioning or cleanliness.
First, check if the solar panel is cleaned. A thin layer of dust or a small (even just 1cm wide) piece of dirt or leaves on the panel
can significantly impact its performance. Use a wet cloth to clean the panel thoroughly.
Second, make sure that no part of the solar panel is in the shade, a small shadow on any part of the solar panel can reduce its
production a lot. Make sure that no tree, branch or construction will make a shadow on the solar panel at any time of the day.
